1 Claim.

This invention relates to improved mechanisms for rocking the wheels ofa car relative to its chassis when lubricating the same and when testingthe same to detect body squeaks and the like.

Among the objects of the present invention, it is aimed to provide animproved mechanism for rocking the wheels of a car relative to itschassis embracing an eccentrically mounted support to receive the wheelsof the car and means for actuating said eccentrically mounted support.

It is still another object of the present invention to provide animproved mechanism for rocking the wheels of a car or the likeconsisting primarily in eccentrica-lly mounted supporting rollers toform the support of the drive wheels of the car, actuated by said wheelsunder the power of the car and cooperating with means for anchoring thechassis against movement relative to the driving wheels and wheel frame.

It is still another object of the present invention to provide animproved mechanism for rocking the wheels of a car or the likeconsisting primarily in eccentrically mounted supporting rollers foralternately raising one wheel relative 25 to the other and forming thesupport for the drive wheels of the car, actuated by a separate drivemechanism when the drive wheels of the car are declutched andcooperating with means for anchoring the chassis of the car against 30movement relative to the wheels and associated wheel frame.

These and other features, capabilities and advantages of the inventionwill appear from the subjoined detail description of specific embodi- 35ments thereof illustrated in the accompanying drawings in which Figure 1is a side elevation of a car associated with one embodiment of thepresent invention;

Fig. 2 is an enlarged fragmental section on the 40 line 22 of Fig. 1;

Fig. 3 is an enlarged fragmental section on the line 33 of Fig. 1;

Fig. 4 is a fragmental enlarged plan of a detail of another embodimentof the present invention;

Fig. 5 is a fragmental side elevation of the structure illustrated inFig. 4;

Fig. 6 is an enlarged fragmental section on the line 66 of Fig. 1; and

Fig. 7 is an enlarged fragmental plan on the 50 line 11 of Fig. 6.

In the embodiment illustrated in Fig. 1, there is shown in dash and dotlines a car I, with the front wheels 2 and rear wheels 3 supported onthe channel bars 4 and 5 mounted on the pairs 55 of standards 6 and l.The channel arms 4 and 5 are preferably provided with the inclinedapproach extensions 8 extending from the supporting ground up to thelevel of the channel bars 4 and 5.

For anchoring the car I against forward movement, the rod 9 is providedhaving a loop 1!! at its forward end to engage the frame cross bar IIintermediate the front wheels 2. The lower face of the rod 9 is providedwith a plurality of loops or hooks l2 to engage the cross rodl3supported by the brackets [4 extending from the sides of the channelbars 4 and 5.

Rearwardly of the rod I3, there is provided the channel bar l5 securedto the lower faces of the channel bars 4 and 5 and extending from one tothe other with the intermediate web of the channel bar l5 provided withtwo rows of holes l6 and H. The holes l5 and I! are provided to receivethe rods l8 and 59 respectively. The rods I 8 and I9 are preferablyexternally screwthreaded to cooperate with the internal threads of thebases 20 and 2! respectively.

At the upper ends of the rods 18 and I9, there are pivotally connectedframe engaging grips 22 and 23 respectively. The rods I8 and IS in turnare provided with the transversely extending pins 24 and 25 respectivelyto facilitate rotating the rods l8 and I9 according to the level to beattained for the claws 22 and 23. Rearwardly of the channel bar l5, seeFig. 3, the intermediate webs 26 and 21 of the channel bars 4 and 5 arecut away to form the openings 28 and 29 respectively conforming to thetransverse section of the supporting rollers 30 and 3| respectively.

The supporting rollers 30 and 3| are provided with lateral flanges 32and the openings 28 and 29 are preferably large enough to afford ampleclearance as indicated to facilitate free rotation of the rollers 30 and3|. The rollers 30 and 3| are eccentrically fixed to the shaft 33 andpreferably fixed as indicated in Fig. 2, so that the lowest level of oneroller will be reached at the same time that the highest level of theother roller is reached. In Fig. 2, the roller 30 in full line positionis disposed at its lowest level while the supporting roller 3| in fullline position is disposed at its highest level. The dash and dot lineposition of the roller 30 on the other hand indicates the highest levelreached while the dash and dot line position of the roller 3| indicatesthe lowest level which it can reach.

With the embodiment illustrated in Figs. 1, 2, 3 and 4, a car I ispreferably driven up the approach 8 under its own power onto the channelbars 4 and 5, and then the hook I0 is positioned on the cross bar H ofthe car with one of its hooks |2 engaging the cross rod I3. Thereuponthe rods l8 and i9 are positioned in the holes l6 and I! which will bein alinement with the side bars of the chassis of the car and thereuponthe grips 22 and 23 raised by manipulation of the cross pins 24 and 25until the grips 22 and 23 securely engage the side bars of the chassisof the car Thereupon, assuming that the drive wheels 3 of the car engageand rest upon the supporting rollers 30 and 3| as indicated in Fig. 1,the engine of the car is started and the drive wheels connected in theusual way to be driven thereby whereupon the wheels 3 willrotatefthelollers 30 and 3| to cause the wheels 3 alternatelytd'be'"raisedand lowered with their wheel frame While the chassis of thecar remains fixed relative tothe channel bars 4 and 5 by the grips 22and 23. While the wheels 3 are so rotated, the rear springs and otherassociated parts may be lubricated and the lubrication freelydistributed over the opposing faces as they are spread from. oneanother. Similarly, while so rotated, an inspection for body squeaks canbe undertaken.

In the embodiment illustrated in Figs. 4 and 5 in place of the rollers30 and 3|, there are provided the rollers 35 substantially identical tothe rollers 30 and 3| and fixed on the shaft 36 which has a worm wheel31 fixed thereon in mesh with the worm 38 mounted on the shaft 39,journaled in the housing 40 and secured to the side of the channel iron4|. The shaft 39 has a gear 42 fixed thereon in mesh with the gear 43 onthe shaft of the electric motor 44.

With this embodiment, the car is driven onto the channel irons 4|similar to the channel irons 4 and 5 with the rear wheels 3 resting onthe rollers 35. In this case, however, the engine of the car is stoppedand the rear wheels declutched when the motor 44 is started and therollers 35 thus actuated by the motor 44 instead of by the power of thecar itself.

With the embodiment illustrated in Figs. 1 to- 4 inclusive, seeparticularly Figs. 6 and '7, the bases 20 and 2| are preferably providedwith two position defining pins 69 and 10 which conform to the openingsI6 and I1 and seat in adjacent openings Hi or H. The cooperation ofthese pins 69 and ill with the openings IE or I! as indicated in Fig. 7anchor the bases 20 and 2| against displacement especially when the rodsl8 and I9 are rotated preparatory to engaging the chassis of the car orafter a greasing job is completed when the claws 22 and 23 are withdrawnfrom engagement with the chassis of the car.

With the same embodiment, see particularly Fig. 2 in order to anchor therollers 30 and 3| against rotation when the car is driven off theelevated support, the pin II is provided to extend through the openingformed in the bearing bracket 12 and an opening formed in the roller 30.It will of course be necessary to turn the roller 30 so that its openingregisters with the opening in the bearing bracket 12 before the pin Hcan be inserted.

It is obvious that various changes and modifications may be made to thedetails of construction without departing from the general spirit of theinvention as set forth in the appended claim.

We claim:

The combination with two parallel rails for supporting the wheels of acar, bearings extending down from said rails, a shaft journaled in rearwheels will in turn actuate said rollers to" heels of thecafalternatelyup and" rock th down relative to its chassis.
